Intravitreal injection has become an indispensable tool for delivering drugs at therapeutic levels to the posterior segment with least systemic side effects. Iatrogenic crystalline lens injury is a rare complication mainly caused by the improper method of administration resulting in contact or penetration of the lens by the needle tip [Figure 1]. The needle should puncture the pars plana corporis ciliaris 3.5–4 mm posterior to the limbus with an oblique insert angle directed at the optic nerve. Precise selection of needle entry points and angles, adequate anesthesia, stable globe fixation, and small-size injection needles are important to avoid such complications.
